General safet
y summary
Review the fo
llowing safety precautions to avoid injury and prevent damage to
this product or any products connected to it.
To avoid potential hazards, use this product only as specified.
Only qualified personnel should perform service procedures.
To avoid fire or personal
injury
Use proper power cord. Use only the power cord specified for this product and
certified for the country of use.
Connect and disconnect properly. Do not connect or disconnect probes or test
leads while they are connected to a voltage source.
Connect and disconnect properly. De-energize the circuit under test before
connecting or disconnecting the current probe.
Ground the product. This product is grounded through the grounding conductor
of the power cord. To avoid electric shock, the grounding conductor must be
connected to earth ground. Before making connections to the input or output
terminals of the product, ensure that the product is properly grounded.

Specifications
This chapter contains specifications for the MDO4000 Series oscilloscopes. All
specifications are guaranteed unless noted as "typical." Typical specifications are
provided for
your convenience but are not guaranteed. Specifications that are
marked with the
symbol are checked in Performance Verification.
All specific
ations apply to all MDO4000 models unless noted otherwise. To meet
specifications, two conditions must first be met:
The oscill
oscope must have been operating continuously for twenty minutes
within the specified operating temperature range. (See Table 12 on page 23.)
You mu st p
erform the Signal Path Compensation (SPC) operation described
instep2oftheSelf Test before evaluating specifications. (Se e page 62, Self
Test.) If the operating temperature changes by more than 10 °C (18 °F), you
must perform the SPC operation again.

Characteristic Description
The formula to calculate the delta-time measurement accuracy (DTA) for a given instrument
setting and input signal is given in the following table. (See Table 3.) The formula assumes
insignificant signal content above Nyquist and insignificant error due to aliasing. The
abbreviations used in the formula are as follows:
SR

= slew rate around 1st point in measurement (1

SR
2
= slew rate a round 2nd point in measurement (2

N =input-referred noise (V

RD = (record length)/(sample rate)

easurement
accuracy
The term under the squareroot sign is the stability and is due to TIE (Time Interval Error). The
errors due to this term occur throughout a single-shot measurement. The second term is due
to both the absolute center-frequency accuracy and the center-frequency stability of the time
base and varies between multiple single-shot measurements over the observation interval (the
amount of time from the first single-shot measurement to the final single-shot measurement).

Characteristic Description
Trigger Coupling Typical Sensitivity
AC Coupling 1 div for frequencies above 45 Hz.
Attenuates signals below 45 Hz.
NOISE R EJ 2.5 times the DC-coupled limits
HF REJ
1.0 times the DC-coupled limits from DC to 5 0 kHz.
Attenuates signals above 50 kHz
Edge-type trigger sensitivity, not DC
coupled, typical
LF REJ
1.5 times the DC-coupled limits for frequencies above
50 kHz. Attenuates signals below 50 kHz
Video-type trigger formats and field
rates
Triggers from negative sync composite video, field 1, or field 2 for interlaced systems, o n any
field, specific line, or any line for interlaced or noninterlaced systems. Supported systems
include NTSC, PAL, and SE CAM.

For all vertical settings, the minimums are:
Trigger type Pulse width Re-arm time Time between channels
Logic Not applicable 2 ns 1 ns
Time Qualified Logic
4ns 2ns 1ns
Logic-type triggering, minimum logic
or rearm time, typical
For logic, the time between channels refers to the length of time a logic s tate derived from
more than one channel must exist to be recognized. For events, the time is the minimum time
between a main and delayed event that will be recognized if more than one channel is used.
For all vertical settings, the minimums are:
Clock active Clock inactive
User hold time + 2.5 ns 2 ns
Minimum clock pulse widths for
setup/hold time violation trigger,
typical
An active pulse width is the width of the clock pulse from its active edge (as defined in the
Clock Edge lower-bezel menu item) to its inactive edge. An inactive pulse width is the width
of the pulse from its inactive edge to its active edge.
The user hold time is the number selected by the user.

Input coupling on clock and data channels must be the same.
For Setup time, positive numbers mean a data transition before the clock.
For H old time, positive numbers mean a data transition after the clock edge.
Setup + Hold time is the algebraic sum of the Setup Time and Hold Time that you
programmed.

For the trigger class width and the trigger class runt, the pulse width refers to the width of the
pulse being measured. The rearm time refers to the time between pulses.
For the trigger class slew rate, the pulse width refers to the delta time being measured. The
rearm time refers to the time it takes the signal to cross the two trigger thresholds again.
